TIME-WHEEL MECHANISM.

SPECIFICATION forming part of Letters Patent No. 792,572, dated June 13,1905.

Application filed November 14. 1904. Serial No. 232,560.

To all whont it may concern.-

Be it known that we, MICHAEL J. DEELEY and ALFRED E. QUINLAN, citizensof the United States, and residents of Sheboygan Falls, in the county ofSheboygan and State of WVisconsin, have invented certain new and usefulImprovements in Time-\Vheel Mechanism; and we do hereby declare that thefollowing is a full, clear, and exact description thereof.

Our invention consists in certain peculiarities of construction andcombination of parts hereinafter particularly set forth, with referenceto the accompanying drawings, and subsequently claimed, the object beingto insure accurate meshing of the worm and worm-gear that have automaticintermittent engagement as parts of a time-wheel mechanism such as iscommon in spinning-mules, this accuracy of meshing serving to preventinjury to the thread of said worm or to the cogs of said gear.

Figure 1 of the drawings represents a plan View of the worm andworm-gear of a timewheel mechanism, said gear and parts in connectiontherewith being in accordance with our invention. Fig. 2 of saiddrawings represents a sectional view on the planes indicated by lines 22 in Fig. 1.

Referring by letter to the drawings, A indicates the worm, B theworm-shaft, O the chambered worm-gear, and D the gear-arbor, in atime-wheel mechanism, such as is common in spinning-mules. The gear C isprovided with a circumferential recess deeper than its cogs and of alength suflicient to receive the worm A, with which it is normally inregister.

Loose on the hub of the gear C and facing the flush side of said gear isa plate E, having an outwardly-bent and toothed outer end that crossesthe recess in the aforesaid gear and projects a suitable distance beyondthe same. Engaging the gear G is a screw F, that extends through alongitudinal slot in the plate E, and a preferably conical spiral springG is confined between said plate and the screwhead.

In practice a starting swing of the shaft B causes the worm A to engagethe recess Z) in the gear G, the pitch-line of said worm passing that ofsaid gear when this engagement takes place. At the same time there isengagement of the worm with the tooth end of the plate E, there beingyield of this plate against resistance of the spring in oppositionthereto. Upon subsequent automatic recovery of the shaft B to bring thepitch-lines of the worm A and gear 0 into proper relation the engagementof said worm with the plate E will cause said gear to start on itsrotary movement, and this movement is continued by the subsequentengagement of the gear-cogs with the aforesaid worm. At a predeterminedtime there is automatic return of the worm and gear to normal position.

Having thus described our invention, What we claim as new, and desire tosecure by Letters Patent, is

1. The worm-gear of a time-wheel mechanism provided with acircumferential recess of greater depth than its cogs and of a lengthsufficient to receive a worm with which it is normally in register, aplate loose on that portion of the hub that extends from the flush sideof the gear, the outer end of the plate being toothed, laterally bentand projected beyond the gear-recess which it crosses to be in the pathof said worm; a screw extending through a longitudinal slot in the plateinto said gear, and a spring arranged between said plate and thescrew-head.

2. The worm-gear of a time-wheel mechanism provided with acircumferential recess of greater depth than its cogs and of a lengthsufiicient to receive a worm with which it is normally in register, anda laterally yielding plate arranged in connection with the gear oppositethe flush side of same to extend across the recess aforesaid and beyondthe same in the path of said worm, the outer end of the plate beingtoothed and laterally bent.

In testimony that we claim the foregoing we have hereunto set our hands,at Sheboygan Falls, in the county of Sheboygan and State of Wisconsin,in the presence of two witnesses.
